UNITED STATES PATENT @FFlCE AUGUSTUS G. OHRISTMAN, OF LITIZ, PENNSYLVANIA.

FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 282,052, dated July 31, 1883.

Application filed March 12. 1883.

To all whom it may concern:

Be it known that I, AUGUSTUS G. CHRIST- MAN, a citizen of the United States, residing at Litiz, county of Lancaster, State. of Pennsylvania, have invented a new and useful Improvement in Feed-Gutters, of which the fol lowing is a specification.

This improvement relates to that class of implements where provision is made for shipment; also, that class where self-sharpening surfaces are provided for the same.

The object of the invention is to furnish a feed-cutter easily separable in its parts for ship ment in knockdown parcels, and to furnish at feed-cutter as prepared for work. Fig. 2 represents a front elevation, plan, and cross-section of the throat-piece, exhibiting the selfsharpening form of the opening. Fig. 3 represents the rear leg-bracket. Fig. 4 represents the knife-lever and gage detached from the cutter. Fig. 5 represents aleg detached from its socket; Fig. 6, an elevation and partseetion of the throat-piece, also elevation and end View of a bed-knife, showing its application, in all of which- A represents the usual feed-cutter box; A, the throat-cover; B, the legs; B, the screws for securing the same to the leg-sockets; G, the throat-piece, provided with bed-knife edge 0; C leg-brackets, having open bolt-slots G; and G, fulcrum-arm; C fulcrum-pin, and G cap. D represents the cutting-knife lever; D, the handle; D the evener; D gage-post; D", re ces's for knife-bolt; D fulcrum-head. E represents the cutting-knife, secured to the lever D by bolts E; F represents the usual gage,

. having a head, F, mounted upon the lever-post F and adjustable thereon by a setscrew, F. G represents the bracket for the back leg, which has a three-sided socket-recess, G, for the leg, with an open slot, G for the bolt B to slide freely therein. H represents a steel or chilled east-iron bed-knife, in section a segment of a circle, having slots H and bolts H-,

to secure the same to thethroat-piece. lVhen a bed-knife is to be used, it is adapted to be applied to the throat by a, curvilinear recess within the front face.

It will be seen that by the arrangement of the open slot in the leg-sockets a slight turn of the screw-bolt B will loosen the leg and permit its withdrawal; the same with the knife-lever and gage. The loosening of a single bolt in either case permits the removal of the piece. The legs, knife-lever, and gage may then be packed within the straw-box A, thus permitting the full freightage of the car, instead of occupying the area of the car, and shipping about one-third of its freight capacity.

In constructing feed-cutters (of the cheapest face meets the outer parallel face, the wear of the knife-lever upon the throat continuallyrenews the cutting-edge of the same. It will be noticed,also,that the interior angular face permits the application of a file thereto, and thus it may at any time be resharpened.

For the hi gher-priced feedcutters I make use ofa steel bed-knife, H, made of a circular section embedded in a corresponding recess in the front of the throat-piece; the curvature of the knife and its cutting-edge being so arranged relative to the face of the throat that as it wears away and has its cutting-edge renewed its adjustment by the bolts H in the slots H will always bring the cut-tingedge in line with the face of the throat, similar to the face presented by the chilled front of the same. The projected fulcrum-post O is formed square on the end, and the cap G is correspondingly recessed, which prevents movement of the cap through the movement of the knife-lever, and therefore the bolt or end screw binding the cap upon the post has no tendency to become loosened. The leg-sockets C are flanged or faced on three sides, the transverse face being slotted from the lower edge, as at 0 for the reception of the screw-bolt B. The legs being inserted therein, the bolt is screwed until it comes in contact with the surface of G which securely connects the leg B with the boX A, and avery slight turn in the reverse direction will permit the withdrawal of the leg by pulling it away from the boX. The bracket G for the rear leg is constructed in a similar manner, and is operated in the same way to connect or release the leg.

The evener D of the lever D receives the thrust of the material being cut, and keeps it even for the next projection of the same to be cut, the gage F being adjusted on the post F to the position to give the desired length to the feed to be cut.

The drawings are so fully' detailed that an expert will easily comprehend the same.

Having shown its novelty and use, I desire to obtain by Letters Patent the following claims on the same:

1. Incombination with a feed-cutter box, A, a throat-piece, 0, provided with the usual knife-arm, C", and leg-sockets C the fulcrumpost 0 having a square shank at or near its outer end, and the leg-sockets having each open bolt-slots O, or bifurcated on one of their faces, the throat C, upon three of its sides, being formed of retracted angular internal faces, as shown, the usual reciprocating knife, E, and evener F, mounted upon the fulcrum-post C and secured thereon by the square-eyed cap ranged to operate as and for the purpose speci- 4o AUGUSTUS G. GHRISTMAN.
